U+1F4ED "📭" Open Mailbox with Lowered Flag Unicode Character

U+1F4ED "📭" Open Mailbox with Lowered Flag is a visual symbol representing a mailbox with its red flag in the down position, which traditionally indicates that no outgoing mail is waiting to be picked up, though it can also simply signify an empty or unraised mailbox flap. In digital communication, this emoji is often used to convey that a message has been received or that an inbox is empty, or more broadly to represent waiting for mail or a lack of pending correspondence. It stands in contrast to the U+1F4EC "📬" Open Mailbox with Raised Flag, which signals outgoing mail or a notification of new messages.
